Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically an air purification device for road construction. Background Technology

[0002] Road construction generally involves repairing, widening, or rebuilding roads. During road construction, the existing roads need to be damaged and modified, which will fill the construction site with dust and cause dust pollution. A large amount of dust in the air will not only affect the construction progress of construction workers, but also directly threaten the life, health and safety of construction workers and surrounding residents. In particular, construction workers in dusty environments may suffer from various cardiovascular and respiratory diseases. Excessive dust can also easily breed bacteria and viruses, which is extremely detrimental to physical health and also poses a great threat to skin health.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN214106314U) discloses an air purification device for road construction, comprising a water tank, a filter box, and a swinging device. A rotating shaft is rotatably connected to the upper surface of the water tank. A support is provided on the upper surface of the water tank, and a hydraulic push rod is rotatably connected to one side of the support. A sleeve is fixedly connected to one end of the hydraulic push rod. A round rod is provided on the lower surface of the filter box, and the sleeve is rotatably connected to the round rod. Filter screens are slidably connected to two opposing grooves on the upper side of the two supports. Ceramic filter plates are slidably connected to two opposing grooves on the lower side of the two supports. An air intake fan is provided below the ceramic filter plate. An exhaust fan is fixedly connected to one side of the upper surface of the filter box. A connecting seat is fixedly connected to one side wall of the filter box, and a swinging device is provided on the connecting seat.

[0004] Although the aforementioned patent enables the air purification device for road construction to have a large purification range and effectively adsorb all dust and bacteria in the air through the setting of the rotating shaft and swing device, the application range is small and it is not suitable for use in outdoor environments such as construction sites, resulting in poor air purification effect and inconvenience of use.

[0005] Therefore, this utility model provides an air purification device for road construction to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides an air purification device for road construction, such as... Figure 1-4 As shown, the air purification device for road construction includes a base 1, a purification body 2 fixedly installed on the upper end of the base 1, an air inlet 3 provided on the upper end of the purification body 2, an air intake hose 4 fixedly installed on the air inlet 3, an air tank 5 fixedly installed on the left end of the air intake hose 4, an air intake fan 6 provided on the upper side of the air tank 5, an air intake nozzle 7 provided on the left end of the air intake fan 6, an air outlet 10 provided on the lower side of the purification body 2, a filter bracket 12 fixedly installed inside the upper end of the purification body 2, multiple filter cartridges 13 movably installed on the filter bracket 12, and a spray assembly provided inside the upper end of the purification body 2.

[0026] Through the coordinated operation of the suction hose 4, air tank 5, suction fan 6, and suction nozzle 7, dusty air from the construction site can be drawn into the purification unit 2. Multiple filter cartridges 13 are used to initially filter and collect dust particles in the air. At the same time, the spray assembly installed in the purification unit 2 can evenly spray water mist into the purification unit 2, thereby effectively adsorbing and settling dust particles in the air, further improving the air purification effect.

[0027] A mobile trolley 8 is fixedly installed on the lower side of the gas tank 5, and multiple sets of casters 9 are fixedly installed on the lower side of the mobile trolley 8.

[0028] The multiple sets of casters 9 make it easy for users to move the gas tank 5 using the trolley 8 and the four sets of casters 9, thus enabling the gas tank 5 to purify the air at different construction sites and improving the practicality of the air purification device for road construction.

[0029] The spray assembly includes a main spray pipe 14, which is fixedly installed on the front side of the purification body 2. A water inlet hose 16 is fixedly installed on the left end of the main spray pipe 14. Multiple groups of flow valves 17 are fixedly installed on the upper side of the main spray pipe 14. Multiple groups of spray branch pipes 18 are fixedly installed on the rear side of the multiple groups of flow valves 17. The multiple groups of spray branch pipes 18 are movably inserted into the purification body 2. The left end of the water inlet hose 16 is connected to an external water source.

[0030] Water from an external water source is introduced into the main spray pipe 14 through the water inlet hose 16. With the cooperation of multiple diversion valves 17 and multiple spray branch pipes 18, the water mist is evenly sprayed into the purification body 2, thereby effectively adsorbing and settling dust particles in the air, further improving the air purification effect. Finally, the treated air is discharged through the air outlet 10, achieving the purpose of purifying the air at the construction site.

[0031] Two sets of inspection doors 11 are slidably installed on the front side of the purification body 2, and the two sets of inspection doors 11 are located on the front side of multiple filter cartridges 13.

[0032] The installation of two sets of inspection doors 11 facilitates users to clean and maintain multiple sets of filter cartridges 13, preventing excessive dust accumulation and clogging of the surface of the multiple sets of filter cartridges 13 after long-term use, thus improving the practicality of the air purification device for road construction.

[0033] A filter 15 is fixedly installed between the left end of the main spray pipe 14 and the inlet hose 16.

[0034] The filter 15 is used to filter the external water source as it passes between the spray main pipe 14 and the inlet hose 16, preventing impurities in the water source from entering the spray main pipe 14, ensuring the purity of the water mist, and further improving the air purification effect.

[0035] The intake hose 4 is composed of a corrugated hose.

[0036] The corrugated hose has good flexibility, which makes it easy to extend and expand the air intake hose 4. At the same time, the corrugated hose has a certain degree of extensibility and can adapt to bending at different angles, thereby improving the flexibility of the air purification device for road construction.

[0037] The lower end of the purification body 2 is tapered at the connection point with the air outlet 10.

[0038] The conical design facilitates the rapid discharge of treated air while preventing dust from flowing back into the purification unit 2, further improving the air purification effect.

[0039] Working principle: During use, the user moves the air tank 5 using the trolley 8 and four sets of casters 9, allowing the suction hose 4, air tank 5, suction fan 6, and suction nozzle 7 to work together to draw dusty air from the construction site into the purification unit 2. The water is then connected to an external water source via the water inlet hose 16. The water flows through the main spray pipe 14 and filter 15 into the water inlet hose 16, and is then diverted into multiple spray branch pipes 18 via multi-group diversion valves 17 installed on the main spray pipe 14. The water entering the spray branch pipes 18 is sprayed into the purification unit 2 in a mist form, effectively adsorbing and settling dust particles in the air. Furthermore, multiple filter cartridges 13 filter and collect the dust particles, significantly reducing the dust concentration in the air and achieving the purpose of purifying the air at the construction site.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
